TRENDS OF PAVEMENT CHARACTERISTICS DURING TWELVE MONTHS OF A DESIGNED EXPERIMENT

THIS PAPER PRESENTS SOME OF THE SIGNIFICANT FINDINGS OBSERVED DURING THE FIRST 12-MONTH PERIOD OF A COMPREHENSIVE 2-YEAR FIELD AND LABORATORY RESEARCH PROJECT. SIXTEEN EXPERIMENTAL SECTIONS WERE CONSTRUCTED AS PART OF A PRIMARY HIGHWAY PROJECT IN UTAH. THE EXPERIMENT CONSISTS OF 5 FACTORS AT 2 LEVELS, EACH INCORPORATED IN A ONE-HALF REPLICATE OF A 2 TO THE 5TH POWER FRACTIONAL FACTORIAL EXPERIMENT. THE 5 FACTORS ARE THICKNESS OF SURFACE COURSE, THICKNESS OF BASE COURSE, RUBBER SOLID CONTENT, ASPHALT VISCOSITY, AND ASPHALT CONTENT. INFORMATION PRESENTED IN THIS PAPER INCLUDES THE FOLLOWING TESTS PERFORMED AT 3-MONTH INTERVALS: TESTS ON PHYSICAL PROPERTIES OF RECOVERED ASPHALT, TESTS OF STRENGTH PROPERTIES OF PAVEMENT MIXTURE, AND TESTS ON THE PAVEMENT PROPERTIES. RESULTS FROM THE TESTS SHOW MUCH SIGNIFICANCE RELATED TO THE 5 MAIN FACTORS OF THE EXPERIMENT. THESE TEST RESULTS ALSO INDICATE THAT MANY CHANGES OCCURRED IN IMPORTANT PAVEMENT CHARACTERISTICS DURING THE 12-MONTH PERIOD. THE INFORMATION CONTAINED IN THIS PAPER CONFIRMS THAT THIS STATISTICALLY DESIGNED FIELD AND LABORATORY EXPERIMENT IS PRODUCING SIGNIFICANT INFORMATION ABOUT MANY OF THE PROPERTIES OF ACTUAL HIGHWAY PAVEMENTS DURING THE FIRST 12 MONTHS IN SERVICE. /AUTHOR/
